2 Claims. (01. 107-9) This invention relates generally to the bread making industry and particularly to a dough twister and power curler.

The main object of this invention is to pro vide a machine for twisting the dough before being placed in the pan for baking for the purpose of changing the grain and closing holes in the dough and retarding the drying action of the bread by the elongation and distortion of the holes.

The second object is to provide a dough kneading machine whereby a more completely uniform texture is insured throughout the entire mass of the dough pieces.

I accomplish these and other objects in the manner set forth in the following specification as illustrated in the accompanying drawings, in which:

Fig. 1 is a side elevation of the machine.

Fig. 2 is a plan view of the machine.

Fig. 3 is a vertical section taken along the line 3-3 in Fig. 1.

Fig. 4 is a vertical section taken along the line 44 in Fig. 1.

Like numbers of reference refer to the same or similar parts throughout the several views.

Referring in detail to the drawing, there is shown a table l9 mounted on the legs I l and I2. Mounted across the ends of the table I9 are the shafts l3 and I4 on which are mounted the pulleys l5 and I6 around which pass the apron ll the top run of which rides upon the table l9.

The apron I! may be driven by any suitable means (not shown) power being supplied through ither of the shafts l3 or l4.

Above the table I9 is mounted the horizontal frame l8, above whose rounded ends I9 and 29 are secured the standards 2| and 22. On the standard 2| is mounted a bolt 23, upon which are mounted the rotatable pulleys 24 and 25 which are of different diameter.

On the standard 22 is mounted a transverse shaft 26 on which are mounted the rotatable drive pulleys 21 and 28. The pulleys 21 equal in diameter the pulleys 24 and the pulley 28 equals in diameter the pulley 25.

The belts 29 pass around the pulleys 24 and 2'! and a belt 39 passes around the pulleys 28 and 25.

Belt tightening pulleys 3| and 32 are mounted on the arms 33 and 34 which are hingedly attached to the frame l8 by means of the pins 35 and 36. Power is supplied to the shaft 26 from any convenient source of power through the 2 sprocket wheel 31 which is secured on the end of the shaft 26.

Mounted on the table I9 are the standards 38 and 39 which support the rolls 49 and 4!, around which is loosely passed the wire cloth belt 42, to which motion is imparted by the roll 49 through its shaft 43 on which is secured a sprocket wheel 44 to which power may be supplied from any convenient source (not shown).

The operation of the device is as follows: Assuming that a piece of dough 45 is fed onto the table 19 by means of the apron I1 beneath the lower run of the belt 42 which is travelling in the opposite direction, it can be seen that the dough will be curled up to form an elongated roll which is carried forward by the apron ll underneath the belts 29 and 39.

It will be noted that the central belt 39 is somewhat thicker than the outer belts 29 and therefore projects somewhat below the outer belts as shown in Fig. 3; that is, placing it in a somewhat more closer contact with the roll 46.

It will also be observed that the pulleys 21 and 28 are on the same shaft 26 and will be driven at the same speed but, having different diameters, the pulley 28 will drive the belt 39 faster than the pulleys 21 will drive the belts 29. The result is the impartation of a twisting motion to the roll 41 throughout the length of its travel toward the discharge end of the machine.

It can be seen from the foregoing that without the use of additional equipment, or the expencliture of time, desirable twisting action is imparted and the texture of the bread is greatly improved.

I claim:

1. In a device for coiling a sheet of dough, an endless carrier belt for conveying sheets of dough on the top run thereof, an endless chain web curling belt including top and bottom runs mounted above in spaced relation to and in alinement with said carrier belt, said curling belt having sufllcient slack in its bottom run for engagement/with said carrier belt when the upper run is taut, means for driving said carrier and curling belts with the upper run of the carrier belt and the lower run of the curling belt traveling in opposite directions, and said curling belt being driven from that end remote from the entrant end of the dough sheets to the curling belt to maintain the slack in the lower run of said curling belt, whereby the dough sheets contact the slack portion of said curling belt to coil said moving sheets of dough.

2. In a device for coiling a sheet of dough, a

horizontal longitudinally movable carrier for sheets of dough, a pair of rotatable rolls mounted transversely above and in spaced relation to said carrier and disposed parallel with respect to each other and spaced apart longitudinally of each other, an endless chain web curling belt trained over said rolls and having sufiicient slack in its bottom run for engagement with'said carrier when the upper run is taut, means for driving the roll remote from the entrant end of the dough sheets to the curling belt for operating the lower run of said curling belt in azdirection opposed to the direction of travel of said carrier, whereby the dough sheets contact the slack portion of said curling belt to coil said 16' 2,479,864

moving sheets of dough.
